ABSTRACT:
A method of manufacturing a columnar shaped piece formed of a thermoplastic matrix with ancillary pieces of a non-creeping hard material embedded therein and cemented by the plastic matrix. The ancillary pieces are essentially overlapping slabs which are substantially parallel to one another and the axis of the columnar shaped piece. Molten thermoplastic blended with solid slabs is extruded in the form of a billet into one end of an elongate mold and rotated around the inner surface of the mold. The extrusion continues until the inner surface is uniformly covered with constituents of the billet.
